8 Claims. (01.163-8) pinsor the like upon perforated cards is a manual operation and the labor cost bears a relatively high ratio to the total cost of the merchandised article.

My present invention contemplates a device which facilitates the manual operation of mounting the pins on the card by permitting theoperator to use both hands in performing the task, the card being automatically distorted and held in such a manner as to greatly facilitate the threading operation.

The objects and advantages of my invention will be apparent from the accompanying drawings and following detailed description.

In the drawings,

Fig. 1 is a fragmentary side elevational view of a work table upon which the device comprising my invention may be mounted.

Fig. 2 is an enlarged top plan view of a fragmentary portion of the table illustrated in Fig. 1.

Fig. 3 is a sectional view taken on line 3-3 of Fig. 2.

Fig. 4 is a face view of a card carryin a plurality of hairpinsthreaded upon said card;

Fig. 5 is a fragmentary top plan enlarged view illustrating the manner in which the pins are guided into the apertures in the card;

Fig. 6 is a detail sectional view illustrating the manner of distorting the card.

Fig. '7 is a view similar to Fig. 6 illustrating a hairpin being threaded upon the distorted card.

Referrin in detail to the drawings, I indicates a work table having top 2 supported by suitable legs 3. of the top 2 by means of any suitable fastening devices (not shown). Intermediate the length of the plate a pair of spaced lugs 5 are formed, said lugs projecting downwardly from the plane of the plate 4. Lugs 5 are provided with apertures B which are disposed inalignment, the two lugs 5 serving as a yoke, the apertures 6 providing bearings for a pivot pin 1. g An aperture 8 is provided in the table top and A plate 4 is secured to the lower surface an arcuate portion 9 formed integral with plate 4 extends upwardlythrough said aperture, the

upper face of the arcuate portion 9 being substantially flush with the upper surface of the table top.

The pivotpinl istransversely positioned upon an intermediate portion-of l ever iltl, said lever being positioned between the lugs 5. 0m end of lever It) carries a set screw I I, said set screw terminating in a hexagon head l2. A lock nut I3 threaded upon the setsc'rew VII and serves'to I lock the set screwin a'desired'position. Adjacent the set screw H a plurality of recesses M are providedin lever H), a coil spring. I5 being positioned in each recess, said coilsprings being confined between the base of the recesses l4 and the lower surface of the plate 4. V 1

on the opposite side of the pivot pin aset screw :6 is threaded intolever II said set screw having a hexagon head [8 andfcarrying a lock nut' I9 whereby the set screw can be locked in a 'desired position. Adjustment of the set screws and 16 controls the arc through which the lever Hlcan rock, the movement of the lever in V a counter-clockwise directionbeing controlled by the set screw I6 and the movement of the lever in a clockwise direction being controlled by the position of set screw 1 l. v

On that side of lever H] which carries set screw l6,-the lever is provided with an offset l9 which extends into a portion of the aperture 8. A circular disk 20 is carried upon a shoulder 2| of the offset portion I!) of the lever it], the disk 20 being adapted to normally protrude through the aperture 8 to anelevation above the surface of the table mp2. The disk 20 is secured to the offset portion I9 of the lever by the means of machine screws 22 which are countersunk in the upper face of the disk 20.

Aportion of the upper face of the disk 29 is provided with a substantially sectoral recess 23. Adjacent the circumference of the disk a segmental rib 24 is formed, said rib being provided with a plurality of radially extending slots 25, the slots being disposed adjacent each other throughout the arc traversed by the segmental rib. A segmental element 26 is secured to the upper face of the arcuate member 9 by means of screws 21 or the like, the segmental element 26 conforming substantially in curvature with the arc of the member 9 and also bein substantially concentric with the disk 20. The face of the segmental element 26 is provided with a plurality of. radial grooves 28 which are disposed in aperture.

substantial registration or alignment with the radial grooves 25 provided in the rib 24.

An aperture 29 is provided in lever I and a link 36 is connected to said lever through said The link 30, at its opposite end, is connected to a pedal 3| pivoted as at 32 to member 33 mounted upon fioor 34.

It can readily be seen that by manipulating pedal 3| lever Ill can be rocked about pivot I in a clockwise direction against the compressive force of springs I5. When the lever I0 is so rocked the disk 20 moves downwardly through aperture 8 until the surface of said disk lies appreciably below the surface of the table top. By releasing the force upon pedal 3|, springs l5 act to rock lever It in a counter-clockwise direction, thus moving said lever until the foot of said screw I6 contacts the lower surface of plate 4. At this point in the travel of the lever the disk 20 will be in the approximate position shown in Fig. 3.

The disk 26 together with the corresponding segmental member 26 is adaptable to facilitate the threading of hairpins or the like upon a card such as card 35. The card 35 is provided with-a plurality of apertures 36 which are disposed in an arc of a circle, said apertures being adjacent an edge of the card 35, said edge also defining an arc of a circle substantially concentric with the arc defined by the apertures 36. The card 35 is adapted to carry a plurality of hairpins 31 so mounted upon the card that the legs of the hairpins lie adjacent opposite faces of the card, and the U-bent portions of the hairpins are positioned in the apertures 36.

In utilizing my invention to facilitate the manual threading of the hairpins 31 upon the card 35, the following operation is carried out. Pedal 3| is depressed thereby rocking lever H1 in a clockwise direction causing disk 20 to move downwardly within aperture 8 in the table top. A pair of spaced guide pins 38 extend upwardly from the face of the disk 20 and are adapted to be engaged with apertures 39 provided in the card 35. By registering the pins 38 with the apertures'39 the arcuate portion of the card 35 will be disposed concentricwith the center of the disk 20 and the apertures 36 will be interposed in alignment with the respective grooves 25 and 28. The radius of curvature of the arcuate edge of card 35 is slightly greater than the radius of curvature of the disk 2|), and consequently the arcuate edge of card 35 overhangs the edge of the disk 20. The inner arcuate edge of the segment 26 has a radius of curvature.

slightly less than the radius of curvature of the arcuate edge of card 35.. Accordingly, when card tive apertures in alignment with the grooves 25 and 28.

In the usual hair-gripping fastener of the Bobby pin type, one leg of the pin is longer than the opposed leg, as indicated at 42 in Fig. 5. With the shorter leg uppermost the end of the lower leg may be positioned in one of the grooves 28, provided in the segmental element 26. The pin 3'! may then be moved radially inwardly. The grooves 28 guide the longer end of the pin into an aperture 36, thus guiding the lower leg of the pin into contact with the rear surface of the card. The end of the upper leg of the pin is usually flared upwardly as shown at 43 in Fig. '7 and consequently, said upper leg slides along the upper surface of the card. In this manner the two legs of the pin 31 are caused to embrace opposite surfaces of the card. As radially inward motion of the pin continues the lower leg of the pin enters one of the grooves 25 and is guided and held in a radial position upon the card 36. The relationship of the two legs of the pin'3'| with respect to the distorted card is clearly illustrated in Fig. 7.

It can readily be seen that with the card 35 clamped between the disk 20 and the segmental element 26 and prevented from moving laterally by the guide pins 38, both hands of the operator are free to move hairpins through the grooves 28 and into engagement with the card. Heretofore, it has been necessary for the operator to distort the card with one hand whileinserting It is to be understood, of course, that any number of arrangements of pins may be utilized merely by changing the shape of the cards and by changing the shape of the disk 20 and guide member 26. If desired, the grooves in the segmental member 26 may be eliminated entirely 35 is positioned upon the face of disk 20, the

arcuate edge of said card will extend beyond the edge of the disk 20 and beneath the inner edge of the segmental element 26. With the card in this position the pedal 3| is released. Under the impulse of springs |5, lever rocks in a counterclockwise direction, thus confining that portion of the card 35 included between the arcuate edge of said card and the arc formed by the apertures 36; As shown best in Figs. 6 and '7, the lower surface .of the segmental element 26 adjacent its inner edge is tapered as at 40. disk 26 moves upwardly under the impulse of springs l5, the card 35 is distorted, as shown best at 4| in Fig. 6. The distortion occurs substantially along the line defined by the apertures 36,

thereby disposing the center lines of the respec- Hence, when the and still some of the benefits of my invention will be obtained. Similarly, it is not essential that a groove 25 in the rib 24 be provided for each pin since only a sufiicient number of upwardly extending portions, that is, division walls between adjacent grooves, be provided to clamp the card into contact with the lower overhanging edge of the member 26. Broadly, my invention contemplates a convenient means for distorting a card along the line defined by a plurality of apertures so as to dispose the axes of said apertures in a plane which approaches a parallel relationship to the plane of the card. The provision, however, of the grooved member 26 is preferable since it facilitates location of the end of the lower leg of the hairpin into the aperture.

A boss 44, extends above the surface of the disk 26 whereby an intermediate portion of the card 35 when in position upon said disk is raised a relatively short distance above the surface of the disk. The boss 44 is preferably so located upon the disk 20 as to be adjacent an edge of the card whereby said edge may be gripped by the hand in removing the card from the disk. However, when the card is filled with pins the pedal 3| is depressed and due to the fact that a portion of the edge of the card is raised above the surface of the disk the operator can conveniently remove the card from the disk. In view of the fact that the boss 44 tends to raise an intermediate portion of the card, a leaf spring 45 is preferably secured as by rivets 46 to a porcause the edge of the card which is to be confined beneath the overhanging portion 4!) to extend above the surface of the segmental member 26, thus causing inconvenience in properly clamping the card.
